Calculates decoherence from radiation on a Bell-state fermion pair by mapping integrated Altarelli-Parisi splitting functions to Kraus operators of an open quantum system.
Quantum information observables in LHC top quark pair production are modified by SMEFT dimension-6 operators in ways that depend on their CP properties, offering a complementary probe beyond standard observables.
Energetic radiation induces decoherence that significantly reduces entanglement in fermion pairs at colliders, with statistically significant signals observable in ttbar(g) at the LHC and tau pairs at Belle II.
In perturbative relativistic 2→2 scattering the concurrence of the traced-out qubit density matrix depends at leading order on the real part of the inelastic forward amplitude.
Links amplitude positivity to S-matrix entanglement consistency for flavored states, analyzes disentanglers, and introduces wave-packet regularization for entanglement expressions.
Semi-leptonic h to VV* decays retain an effective two-qutrit description for quantum tomography and entanglement after including finite fermion masses and NLO corrections.
Transverse polarization in e+e- collisions generates maximally entangled fermion pairs in QED processes and boosts entanglement in electroweak and Bhabha scattering.
Simulations of pp to tau+ tau- at the LHC with ML neutrino reconstruction show Bell nonlocality above 5 sigma, proposing tau pairs as a new benchmark system for quantum information studies.
Under mild assumptions, local hidden variable theories become testable at colliders and can be disproved via Bell-like inequalities for muon and tau pairs.
A review summarizing advancements in probing quantum entanglement and Bell inequalities using high-energy particle colliders.
